small circuit breaker breaker DZ47 short-circuit protector for household total open air switch
The DZ47 circuit breaker, or the small circuit breaker, is one of the plastic case circuit breakers. It is the most widely used terminal protection device in building electrical terminal distribution device. For single phase and three phase short circuit, overload, overvoltage protection and other protection under 125A, it includes four kinds of monopolar 1P, bipolar 2P, three pole 3P and quadrupole 4P.
Use of attention
1. There should be no significant vibration and shock at the . installation.
2. check whether the technical parameters on the pad are in line with the requirements.
3. the insulation resistance between the pole and pole (except the monopole), the end and the outlet end of the circuit breaker should be not less than 2M Omega, and the insulation resistance between the pole and the shell, the pole and the installation rail should not be less than 5M Omega. If the product is not required, the product shall not be used and should be exchanged in time with the supplier.
1.High capacity of rated short circuit
2. double connection function. It can connect standard remittance and soft conductor conveniently.

Working principle of product
A small circuit breaker is the principle that the bimetal bending is directed regularly with the increase of temperature. When the circuit breaker is closed in normal working condition, the internal bimetallic sheet is heated by a certain current, and the thermal expansion coefficient of the two bimetalles is different. It is not enough to release the release mechanism. When the line appears general overload, when the overload current is reached, the bimetallic sheet has a larger bending angle and a lever in the release mechanism, which is enough to push off the release mechanism, and from the small circuit breaker, it plays the role of super load protection. The size of the bimetallic strip is different from that of the small circuit breaker.
Thor is following the international quality system standards, is ISO 9001 certified and our technical standards are in line with GB18802.1-2011/IEC61643-1.
